BUMPER FOR AUTOMOBILES.

Specification of Letters Patent.

application filed September 18, 1920. Serial No. 411,196.

To all whom it may concern:

Be it known that i, JorrN Drums, :1 citizen of the United idtates, resi. .ling at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Bumpers for Automobiles, of which. the following is a specification.

This in vention relates to bumpers for automobiles, and more particularly to means for securing a bumper to the nine of an automobile.

The objects of the invention are to provide means of improved construction for mounting a bumper on the frame of an automobile in such a manner that the bumper can be readily mounted on the automobile or removed therefrom; also to provide an a."- taching device for securing the bumper to a transverse frame member of an automobile; also to improve the construction of attaching means of this kind in other respects hereinafter specified.

The attacl'iing device isjshown in the accompanying drawings as applied to the front transverse frame member of a Ford automobile, while the attaching device is primarily intended to be used in connection with. Ford automobiles, yet it is not intended to limit the invention to such use.

in the accompanying drawing"?- Flglll'fi 1 is a fragmentary perspective view of an automobile frame and a bumper and the improved attaching means embody ing the invi-mtion.

Fig. 2 is a sectional line 2-2, Fig. i.

Fig. 3 is a sectional plan thereof on line .3-3 Fig. 1.

Fig. lis a sectional elevation thereof on line 4-4, 1.

Fig. 5 is a perspective view of the wedge bolt thereof.

Fig. 6 is a perspective view of the attach ing bracket thereof.

Referring to the drawings 10 deshenates a bumper which may be of any suitable construction. In the embodielcvation thereof on meut illustrated the bumper comprises a bumper bar 11, =a -h side of which is clamped between a pair of spring members supported by a rearwardly extending arm 13. (lnly one side of the bumper and vehicle frame is shown, it being understood that similar supporting means r re provided for the other side of the bumper.

tionar v wedge The bumper bar and spring supporting means may be of any suitable type, the only requirement being that the bumper have rearwardly projecting arms for attachment I to the bracket.

According to the invention, the attaching means for securing the bumper to the aut0- mobile include a bracket member which consists of a. plate member 14, having an arm extending therefrom on which the arm 13 of the bumper may be seated and to which it is attached by suitable means, such as bolts 16. The arm 15 may, if desired, extend outwardly from the plate member 14 at an angle thereto, as shown in the drawings. The outer face of the angular arm 15 is preferably? grooved as at 17 so that the arm 13 will fit snugly tlierein. The plate member 14 is preferably shaped to conform to the shape of a channel member 18 of the frame and is formed with a flat inner face 19. lVhen it is desired to secure the bumper attaching means to the Ford automobile, the

fiat inner face is preferably provided with recesses 20 therein to receive the usual rivet heads 21 projecting from the overlapping end piece 22 of the channel, and the inner face 19 of the plate member is also provided with a longitudinal shoulder or rib 28 on which the lower edge of the end piece 22 rests. A bridging beneath the plate member 14 and this bridging portion carries a guide member or staportion which is adapted to be positioned between the flanges of the channel beam, the lower edge of the channel flange 18 resting upon the bridging portion 24- in which position the parts straddle the lower edge of the flange 18. The fixed guide member or wedge portion 25 is formed with an inclined or wedge face 26 which communicates with a hole 27 through the bridging portion 24.

The bracket is secured in place on the channel beam by means of a wedge bolt 28 provided with a. threaded shank extending through the hole. in the bridging member and a flaring or tapered head 29 providing a wedging' face. The bolt is provided with a nut and upon turning the nut upon the bolt the bolt will be moved downwardly. the wedge face on the bolt cooperating with the inclined or fixed wedge face 26 to wedge the bolt tightly against the inner side of the channel flange 18 and to draw the face 19 of the plate member l-l tightly against the end piece 22 of the frame. In such position, the rivet heads 21 which project into recesses 20, together with the wedging action of the bolt will effectively prevent movement of the bracket relatively to the channel.

To secure the bracket to the frame channel, the bolt is placed. in its guidepart and the shank of the bolt held from projecting from the hole 27. The'bracket is then placed upon the flange 18 of the channel, with the face 19 in contact with the overlapping end piece 22 and the rivet heads 21 in the recesses 20. The belt is then allowed to drop down and the nut is secured on its projecting end. Tightening of the nut will wedge the parts together as aforesaid. \Vhile the bracket is most securely held against detachment from the frame channel, it may be readily and easily removed by loosening the'nut whereupon the bolt may be forced upward, the head sliding up its slideway until it ceases to contact with the flange member 18, whereupon the bracket may be withdrawn from the flange.

I claim as my invention:-

1. In combination with a frame channel- ;of an automobile, an attaching member comprising a part adapted to enter between the flanges of said channel and a part engag ing the outer side of one of said channel flanges,-and a member having a seating in saidfirst member and bearing upon the in n'er side of said channel flange for wedging said second part against sald channel flange. 2. Ina devicefor attaching a bumper to a vehicle frame member having a flange,

the combination of two parts movable relatively to each other, one of said parts straddling said flange and engaging one side. thereof and the other part contacting with the other side of said flange, cooperating inclined faces on said two parts, whereby movement of said two parts relatively to each other causes said parts: to be wedged tightly against opposite sides of said channel flange, and an arm on one of said parts to which said bumper may be attached.
